Dr. Ir. Noor van Andel, former head of research at Akzo Nobel, recently presented a talk at the Dutch Meteorological Institute KNMI, concluding there is

• No observational evidence for influence of CO2 on past or present climate

• Rising Outgoing Long-wave radiation with more than 3.7 W/m^2 per ºC SST cannot be the effect of rising CO2 or of the increase of other “greenhouse” gases. Rising OLR/SST with 8.6 W/m^2K means that the atmosphere has become more transparent to IR radiation in the past 60 years. The “greenhouse effect” has become less.
